Patented May 29, 1906.

I Application filed March 13, 1903. Serial hi0. 147.663.

To all whom it may concern: I

Be it known that 1, JOHN B. LEONARD, a citizen of the United States, residing at Memphis, in the county of Shelby and State "of Tennessee, have invented certain new and useful Improvements in Antislip age Dressing for Belting, of which the foilowingis a specification.

My invention relates to compositions designed to render belts antislipplng; and the object of the invention is to provide a composition of this character for the various kinds of beltings, which when applied will rovide the surface of the belting with a flexib e wearing-film of such a degree of hardness as to prevent the absorption by the belting of the oil contained in the composition of the film, the

absorption of which destroys the original character of the composition and is injurious to the belting. 1

The composition of the invention, while producing an anti'slippage wearing-surface, is

also designed to serve as a protectin -fi1m to preserve the belting, as by itsuse t e moisture and oil are revented from enterin into the pores of the belting, and the nature condition of the belt material is maintained.

' In forming the com osition I employ, in substantially the following proportions, rosin three parts, beeswax two parts, and tallow or neats-foot oil five parts and combine these ingredients by subjecting the same to steamheat, such heat being used for the reason that the effect of fire-heat is to destroy the adhesive qualities of the composition. The resultant is a'semih'ard mass when cooled and which-for its application upon beltin must be heated and applied while in a fiui state, so as to enter sufficientl into the, surface pores. ofthe belting and be distributed in a thin coating over thesurface; To secure the pro er distribution of the composition, it is pre erably applied to the belt ng while the same is inmotion. This compos1tion leaves the belting with a smooth. and apparently hard yet very. adhesive and elastic film,

which is so efiicient for the pur oses intended that the belting can be run-w le very loose without the possibility of any slippage occurrin l t will be observed that in using an animal oil, such as tallow and neats-foot oil, a softenin agency is employed which has a natural a nity for leather and other beltingmaterial and is, moreover, rendered the less 1n ur1ous by reason, of the fact that this softening agency is incorporated in the composition in such a manner and in such proportion as to practically prevent its absorption by the beltmg, though insuring the complete filling of the surface pores bythe composition when roviding belting with an adhesive surface.

he present'invention, however, is distinguishedfrom a stufling composition, as the composition of the invention does not enter into the structure of the belting material, but

merely surfaces the belting after the manner of a varnish, and the composition of the 111- vention is distinguished from antlsllppage dressings employing the ingredients of the invention in that such dressm s are in the nature of pastes which are app ied cold and are open to the objections which the present 1nvention is designed to obviate. It will therefore be seen that a surface dressing has been produced of such character and consistency as to be retained by the ores of the belting material without being a sorbed throughout the fibrous structure thereof, which absor tion causes the oil to be extracted from t e rosin and renders the composition ineffective, While injuring the belting. What I cla1mis I An antislippa e composition for belting, consisting of, an in the proportions, substantially, rosin, three parts, beeswax, two parts, and animal oil, five arts, said composition being ada ted for app ication by melting and to form w hencold a tough, elastic and non- 1absorbable skin or coating-for the belt-surace.
